NAME
       chkmadd.exp - CHecK Mail ADDress with EXPect

SYNOPSIS
       chkmadd.exp [ -V | REMOTE_HOST EMAIL_ADDRESS [TIMEOUT] ]...

DESCRIPTION
       Verifies  EMAIL_ADDRESS  by  talking SMTP to REMOTE_HOST via telnet(1).
       Requires the expect(1) scripting language, a  Tcl  (Tool  command  lan-
       guage) extension. This script is usually invoked by the chkmadd(1) pro-
       gram which determines the respective mail  exchanger  (MX)  for  e-mail
       addresses  to  be  used  for  REMOTE_HOST.  If available, read the chk-
       madd(1) man page or enter chkmadd for details.

OPTIONS
       -V     Display version information and exit.

       REMOTE_HOST

       EMAIL_ADDRESS

       TIMEOUT
              Number of seconds after a delay is considered  a  timeout.   The
              default is 10.

EXIT CODES
         0    Address  verification  positive  or  version  info  successfully
              retrieved

       Standard shell script disclaimer blurb thing:

       This  script  is a hack.  It's brute force.  It's horrible.  It doesn't
       use Artificial Intelligence.  It doesn't use Virtual Reality.  It's not
       perl.   It's  not  python.   It  probably  won't  work unchanged on the
       "other" thousands of unices.  But it worksforme.  --ramiro
